I just want to make some suggestions about player movement and incorporation of camera bobble. I really hope there will be a sprint function, sprinting would be the perfect opportunity to incorporate some camera bobble.
I also had an idea based on the early trailer with the famous "clothesline" scene. When he turns to look at the civilian up in the window I kind of noticed the rifle go down a little and then it seemed like the player was moving his head not sinchronized with the body and the rifle but just neck up, I think this would be a great feature, it could be as simple as binding the function to a single key that would break the sinchronization and only turn the head. this would be a super realistic feature and would make a breakthrough. OF course this would also be a good feature to use the camera bobble with. I don't think the bobble should be a constant but more dynamic, i.e. as you turn or strafe the camera tilts, the faster you turn the more exagerated the camera tilt should be.
Whn you saprint a certain cmaera movement should kick in, that tilts side to side on a diagonal but also that tilts slightly up and down, but not bouncing up and down like in the the 13 min e3 demo but more of a pivot as if it was on a fulcrom. I really think features like this would take it up a knotch.

Yeah, i would LOVE to see a head turning feature, and perhaps just poking your head around corners would be good, and maybe binoculars as well.
